Anybody installing PHP 5.4 from the ZIP file on php.net (not the precompiled binary from Aprelium) will need to select one of the registry settings to import from inside of the ZIP archive. Otherwise, you will get 503 errors from Abyss. You can double check your config by running php.exe (as opposed to php-cgi.exe) from the command line. There should be no output, ctrl+c to end it._________________Security Blog
